[alsa-devel] ASoC: fsi: Add FSI DMAEngine support

[Kuninori Morimoto]

Hi Mark, Liam, and Paul

These are DMAEngine support for FSI driver

I created a lot of patches since FSI DMAEngine needed much modification.
I hope it was good for reviewing.
But some patches are just cleanup/tidyup/rename.
Last patch is main DMAEngine patch. it support Tx case only at this point.

FSI will use PIO version if CPU/platform doesn't have DMAEngine support.

Could you please check #16 patch which modify arch/arm/mach-shmobile and arch/sh
